Hi there.
00:03
In this question, we are starting with the moles of the substance, and we are trying to convert to mass.
00:12
Anytime we are converting from moles to mass, or for that matter, from mass to mole, we need to use the molar mass of the substance.
00:21
And molar mass is the mass of one mole of the substance in grams.
00:26
We determine that molar mass by using the masses from the periodic table.
00:31
So in this question, we have sucrose, which is c12, h -22, 011.
00:44
So to calculate the molar mass of this, we need to look at the periodic table and add together the mass of 12 carbons plus 22 hydrogens plus 11 oxygens.
00:55
That mass ends up being 342 .30 grams.

Okay, so we have the molar mass now...
